The number of pods on a given node is determined by the --max-pods=k
directive. When the address space is exhausted, no more pods can be
scheduled even if from the --max-pods-perspective, the node still has
capacity.
The special case that a pod is scheduled and uses the node IP in the
host network namespace is too "soft" to derive a guarantee.
Comparing kubelet_max_pods with kube_network_node_prefix when given
allows to assert that pod limits match the CIDR address space.
* Move front-proxy-client certs back to kube mount
We want the same CA for all k8s certs
* Refactor vault to use a third party module
The module adds idempotency and reduces some of the repetitive
logic in the vault role
Requires ansible-modules-hashivault on ansible node and hvac
on the vault hosts themselves
Add upgrade test scenario
Remove bootstrap-os tags from tasks
* fix upgrade issues
* improve unseal logic
* specify ca and fix etcd check
* Fix initialization check
bump machine size
* sysctl file should be in defaults so that it can be overriden
* Change sysctl_file_path to be consistent with roles/kubernetes/preinstall/defaults/main.yml
The openssl package on Tumbleweed is actually a virtual package covering
openssl-1.0.0 and openssl-1.1.0 implementations. It defaults to 1.1.0 so
when trying to install it and openssl-1.0.0 is installed, zypper fails
with conflicts. As such, lets explicitly pull the package that we need
which also updates the virtual one.

While `do` looks cleaner, forcing this extra option in ansible.cfg
seems to be more invasive. It would be better to keep the traditional
approach of `set dummy = ` instead.
The current way to setup the etc cluster is messy and buggy.
- It checks for cluster is healthy before the cluster is even created.
- The unit files are started on handlers, not in the task, so you mess with "flush handlers".
- The join_member.yml is not used.
- etcd events cluster is not configured for kubeadm
- remove duplicate runs between running the role on etcd nodes and k8s nodes
